Capabilities

Third-party cyber risk

Identify which external digital dependencies create material cyber exposure and concentrate oversight where consequences are greatest.

Know which external dependencies could carry a cyber event into the enterprise before treating every supplier as equal

We connect third-party access, critical dependencies and cyber exposure to identify which external relationships can create material business consequences.

Organizations increasingly depend on technology providers, cloud platforms, software vendors, service partners and interconnected suppliers that sit outside direct security control. Traditional third-party programs can produce large volumes of questionnaires and ratings while providing limited clarity about which relationships could actually transmit material disruption or compromise. Cyber exposure depends on what a third party accesses, the services it supports and how easily failure can propagate into critical operations. Risk intelligence must therefore prioritize dependencies by consequence and continuously reassess them as relationships, technologies and external conditions change.

Focus

Third-party cyber exposure extends beyond vendors directly connected to the business

Suppliers, platforms and service providers create dependencies that can transmit disruption across enterprise boundaries.

Strategic Challenges

Which external dependencies could create material cyber consequences for the business?

The challenge is distinguishing critical relationships from a large vendor population with very different risk profiles.

Strategic Impacts

Risk-based oversight concentrates attention on the third parties that matter most

Criticality, access and dependency analysis helps align assessment depth with potential business consequence.

Read now

Observed Patterns

Third-party programs often collect questionnaires without testing real dependency

Compliance evidence can appear reassuring while concentration, access paths and recovery assumptions remain unexplored.

POV

A completed vendor assessment does not mean the dependency is understood

Third-party risk should be judged by exposure and recoverability, not by the amount of documentation collected.

Our approach

Prioritize external cyber exposure according to dependency and consequence rather than supplier count

Our approach begins by identifying third parties with access to critical data, systems or operations and mapping the dependencies through which their compromise could affect the enterprise. We distinguish material cyber relationships from vendors whose failure would have limited consequence, then assess access, control conditions, concentration and resilience around priority dependencies. Contractual and assessment mechanisms are examined alongside technical exposure rather than treated as sufficient evidence of security. We establish differentiated oversight, monitoring and escalation according to the evolving risk each external relationship creates.

The data and estimates presented are indicative and intended for illustrative purposes. Actual outcomes may vary based on each company’s specific context, market conditions, operating model, implementation choices, and the quality and consistency of execution, including actions undertaken by the client.

Keypillars

Explore the key pillars that define this capability and shape how we create focused, measurable business impact.

Dependency visibility

Maps critical suppliers, digital connections, data access, and technology dependencies that can transmit cyber risk into the enterprise

Risk differentiation

Segments third parties according to access, criticality, concentration, substitutability, and potential operational or information-security impact

Ongoing assurance

Combines due diligence, contractual controls, monitoring, reassessment, and escalation across the lifecycle of material third-party relationships

How we help

Concentrate cyber oversight on the external relationships capable of creating material enterprise exposure

We provide third-party cyber risk strategies focused on critical technology, service and supply dependencies. The work can include third-party segmentation, dependency mapping, access analysis, concentration risk, security assessment design, continuous monitoring and escalation frameworks. Outputs identify which external relationships deserve deeper oversight, how compromise or disruption could propagate into critical operations, where contractual assurance differs from actual technical exposure and how monitoring and control requirements should change as dependencies and third-party risk evolve.

Organizations depend on suppliers they do not control directly, while those suppliers may access critical systems, services or data.

Prioritize suppliers with access to sensitive data, critical systems, essential services or dependencies that could cause material disruption.

Evaluate access, data exposure, control maturity, dependencies, incident history and the consequences of supplier failure or compromise.

No. They provide evidence, but material risks may require technical validation, contractual controls and ongoing monitoring.

Identify material subcontractors where possible and assess whether concentration or hidden dependencies increase exposure beyond the direct supplier.

Define security obligations, incident notification, access, data handling, audit rights and responsibilities during disruption or termination.

When services, access, ownership, threat exposure or supplier conditions change, and periodically according to materiality.
